Rootkit

A rootkit is a type of malicious and stealthy computer software designed to provide an attacker with access to a computer system without being detected. It is typically used to gain root access to a system so that other malicious activities can be performed. It can be used to hide and gain control of remote systems, intercept network traffic, and override existing system authentication.

Rootkits are designed to do two main things: gain covert access to computer systems, and hide their presence. They can be installed on computers either by a local user with administrator privileges, or even remotely by a malicious actor over the internet. Once a rootkit has been installed, it can then be used to hide the actions of the attacker by concealing any new files that have been added or modifying how existing programs display output.

In addition to being used to carry out malicious activities on a computer, rootkits can also be used to defend against malware. For example, they can be used to stop a virus from writing itself to disk, or to protect certain system services from tampering.

Because they can be used to do both good and bad things, rootkits need to be handled with caution. It’s important to ensure that the rootkit you are using is up-to-date and secure against attack, and that you understand the risks associated with using them. It’s also important to note that rootkits are often capable of bypassing anti-virus programs, so it is strongly recommended that you have an additional layer of security in place.
